Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Clam Soup
Ingredients
Directions
Prepare
Drain the chopped clams in a colander.
Pare and chop the potatoes finely.
Make the soup
In a pot, combine the potatoes and onions with the milk and boil for 15 minutes.
Mix the butter and flour until creamy, then add to the pot and cook for 8 more minutes.
Stir in the parsley, salt, pepper, and a dash of nutmeg, and cook for an additional 3 minutes.
Add the clams and bring to a boil, then remove from heat and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main seafood flavor and the character of the soup.
- Milk
- Forms the liquid base of the soup and gives it a creamy body.
- Potatoes
- Add starch and body, helping the soup feel thick and substantial.
- Butter
- Adds richness and fat, carrying flavor and smoothing the texture.
- Flour
- Thickens the milk as it heats, giving the soup a creamy consistency.
The step that matters
Adding the clams and bringing to a boil. Clams become tough and rubbery when overcooked. Adding them at the end and heating only until they open and the soup is hot helps keep them tender.
Swap the onion
How well each one fits the dish's main ingredients (clam, milk, butter, parsley, potato, flour, pepper):

Fit is the average pairing score against clam, milk, butter, parsley, potato, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
